【摘要】 为了克服金属杂质对电解质溶液复介电常数测量结果的影响,分别对不同位置与数量的金属杂质对氯化钠溶液复介电常数测量的影响进行了数值分析。计算结果表明:金属杂质对电解质溶液复介电常数测量值的实部影响很小,而对虚部影响较大,且金属杂质对虚部的影响随着探头表面的金属杂质数量的增加而增大。更多还原

【Abstract】 The simple and valid method to measure the complex permittivity of electrolyte solution is using an open-ended coaxial line.Because a few metal impurities usually exist in electrolyte solution,they may affect the accurate measurement of complex permittivity of electrolyte solution.The influence of metal impurities on the measurement of complex permittivity of NaCl solution with different positions and quantities is numerically analyzed in this paper.The simulation results show that metal impurities have less influence on the real part of the complex permittivity,whereas they have great influence on the imaginary part,and the influence on the imaginary part is increased with the quantities of metal impurities near the probe.更多还原
